Application October 16, 1956, Serial No. 616,211

2 Claims. (Cl. 33-85) The present invention relates to an improved chalk line holder which is such in design and construction that it will better serve masons, carpenters and others called upon to use a chalk line in the course of their daily work requirements.

A survey and studied consideration of the art to which the invention relates has, of course, revealed that many and varied styles and forms of chalk line and cord holders have been devised and offered to masons and carpenters for use. It follows that the instant concept has to do with a structurally novel chalk line holder which is characterized by distinctive features which more satisfactorily and successfully serve the intended purposes of users of chalk lines.

Another object and aim is to provide a structurally distinct chalk line holder in which manufacturers will find their manufacturing requirements and economies met and users will find their varying needs not only aptly taken into account but likewise effectually met.

Briefly, the improved holder is characterized by a rigid body member. This may be and preferably is of rod-like form. It has means at the outward end whereby it may be expeditiously, detachably and temporarily anchored on a stationary wall or an equivalent structure. It has means at the inward end whereby the cooperating end of the chalk line may be manually hitched thereto and'subsequently readily removed therefrom, said last named means facilitating the essential step of tautening the chalk line to the desired degree.

More specifically the invention pertains to a one-piece rigid rod-like body member having a nailing hole which is usable whenever necessary or desired.

It also has a neck-like shank at the inward end, said shank terminating in a split eye. The eye is disposed in a plane substantially parallel with the plane of the body member and assumes a position at approximate right angles to the adjacent cooperating shank. There is also a neck-like shank formed with and extending laterally from the outward end of the body member and this is situated in approximate parallelism with the first named shank and functions as a shoulder-like work engaging abutment. It is provided with a novel knife-like portion which projects and functions as an anchoring detent, the latter being adapted to embed itself in the work surface in a manner so that it will stay put.

Then, too, novelty is predicated on the provision of a second eye, split or not, which is carried by and extends outwardly from the end of the second named shank and which functions as a finger-piece to assist in handling the device and also, if desired, as a further means for fastening the terminal of that portion of the chalk line which has already been connected by a half-hitch, or otherwise,

to the first named eye.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying sheet of drawings.

In the drawings wherein like numerals are employed to designate like parts throughout the views:

2,302,270 Patented Aug. 13, 1957 Fig. 3 is a top plan view of the structure seen in Fig. 2;

and

Fig. 4 is a fragmentary view, with portions in section, showing the structural details of the cooperating chalk line holders.

Referring to the drawings the wall, building or other structure with which the invention is used is denoted, in a general way, by the numeral 6. The vertical surfaces of the structure with which the holders directly cooperate are denoted by the numerals 8. Since chalk line holders are employed on floors and other structures generally speaking, no further description of this aspect of the invention need be given here.

It is evident that the holders are usually employed in pairs. Each holder is the same in construction andv therefore a description of one will suffice for both. To this end each holder is denoted, as an entity, by the numeral 10. As before mentioned the holder is of one-piece construction and the central body member is denoted at 12 and is preferably of rod-like form. At a suitable place it is provided with an appropriate nail hole 14. In some instances it may be desired to nail the holder on a Wooden building, for which reason the nail hole is provided. The inward end of the body member is provided with a right angularly directed neck-line extension 16 and this terminates in a right angularly disposed split eye 18 the split or slit of which is denoted at 20. It is to be pointed out here that by having this slit the end portion of the line may be more readily applied and attached, as is obvious. A similarly formed and laterally directed neck-like shank 22 is provided at the outward end of the body member and here again this possibly terminates in a lateral outstanding split eye 24 the slot or slit of which is denoted at 26 and which functions as stated. In fashioning this shank and eye the shank is recessed or otherwise formed at 28 to define a relatively thick projecting edge portion which is sector-shaped in plan, as evidenced from Fig. 4. This edge portion is so constructed that it defines a knifelike edge 30 which in turn functions, obviously, as an anchoring detent. That is to say the edge when properly applied embeds itself in a wooden surface and clings similarly to a brick or masonry finished surface and effectually anchors the holders and prevents it from accidentally slipping and becoming displaced.

It will be evident, as is true in many similar situations, that the users may differ in the manner in which they use the invention. For example, one might desire to simply form a knot (not shown) in one end of the chalk line and attach the knotted end to one of the eyes, for example, the eye 18 at the left in Fig. 1. It is believe that, for the most part, it is better to follow the preferred method of use which is illustrated in the drawings. Here it will be seen that the chalk line A is to be primarily stretched between the two inwardly disposed eyes 18-18. Actually the portions of the line adjacent these eyes may be wrapped or wound around the notched portion 16 of the eye as denoted at B. The portions C may then be carried along the body member 12 in each instance. The portion D may then be connectedby a half-hitch to the eye 24 having been passed through the slot 26. The very terminal of the line is then used for grip to pull the over-all line A tight. The eyes 24 may also serve as handy finger-grips as is obvious.

The foregoing is considered as illustrative only of the principles of the invention, Further, since numerous moditir t n l nd a es l readi 9 .914! 99. those ski led in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and acco di y, a l i pd fi ie and equ va may be resorted to, falling Within the scope of the invention as claimed.

What is claimed as new is as follows;

1. A chalk line fastener and holder comprising a onepiece rigid rod-like body member having a nailing hole and a first integral lateral neck-line shank at the inward end of the body member, said shank terminating in a split eye disposed in a plane substantially parallel with the plane of the body member and assuming a position at right angles to said shank and also projecting to a position beyond said inward end, and a second neck-like shank extending laterally from the outward end of said body member and located in approximate parallelism with the first named shank and constituting a shoulder-like work engaging abutment, said abutment having a complemental knife-like portion functioning as an anchoring detent, the latter being adapted to embed itself inthe work surface in a manner to stay put.

2. The structure defined in claim 1 and wherein the last named shank is provided with an outstanding eye which is disposed in a plane which is substantially parallel to the plane of said body member.
